A power outage at Mount Auburn Hospital in Cambridge, Mass., occurred after both electrical cables serving the hospital in a redundant Eversource system failed, according to an article on the Cambridge Day website.
The hospital didn’t return to normal until about 10 1/2 hours after the power went out.
Because of “the high temperature, we could not resume normal operations, as some of our diagnostic equipment needed to cool before being brought back on line,” a report from Mount Auburn to the state Department of Public Health said.
One cable failed around 8:30 a.m. The other went out three hours later, killing power. The hospital’s emergency backup generator system kicked in after that, but it didn’t have the capacity to maintain cooling equipment in every area.
